 Binding Group: In this group we put fused protein scFv-eGFP and fused protein 
 Antigen-Mcherry together into the environment. The two proteins are expected to 
 bind with each other. There will be 9 “Binding Groups” and each of them uses one of 
 the 9 different Antigen-Mcherry fused proteins (9 different antigens: The origin 
p185her2/neu ECD and its 8 mutants). The FRET efficiencies in these groups are called 
 Ebdo” and Ebd(1-8). (Ebdo for the group using the origin p185her2/neu ECD and 
 Ebd(1-8) for the 8 mutants)
